The Kepner Tregoe (also KT-analysis called) is a method for problem definition.

She applies, where a product is to fulfill different criteria well and a prioritization of the criteria is desired.

In the KT-analysis for the criteria a n is set up \ times n matrix, and compared in sequence each criterion with all other criteria.

If the criterion is more important in the line m than in the appropriate column k, then a 1 is registered into the matrix, otherwise 0. The main diagonal of the matrix is filled up with ones. To the sum of all array elements s always applies

s = n \ left (\ frac {n-1} {2} +1 \ right).

In the described variant there is not the possibility that two criteria are equivalent important.

Finally line by line the points are added and divided by s. The result results in the proportional importance of the appropriate criterion.

Example of a matrix:

 Criterion 1. 2. 3. 4. 5. Points rank percentage -------------------+------------------+-----------+-----------+----------- 1. Content | 1 1 0 1 0 | 3 | 3 | 20.0% 2. Products | 0 1 0 0 0 | 1 | 5 | 6.7% 3. Location | 1 1 1 1 0 | 4 | 2 | 26.7% 4. Social security benefits | 0 1 0 1 0 | 2 | 4 | 13.3% 5. Working climate | 1 1 1 1 1 | 5 | 1 | 33.3% -------------------+------------------+-----------+-----------+----------- 15 100.0% 

If the criteria are priorisiert, thereby the evaluation of different solution variants can be made on the basis the degree of completion of the criteria.

Often the KT-analysis is called in connection with Six sigma.

The appropriate problem solution process consists of the 5 elements:

• '' D efine '' (define)
• '' M easure '' (fair)
• '' A nalyze '' (analyze)
• '' I mprove '' (improve)
• '' C ontrol '' (steer)
